 Solubility System: 1,2-Diphenylbenzene with Benzene

---

Components:
   (1) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
   (2) 1,2-Diphenylbenzene; C18H14; [84-15-1]  NIST Chemistry WebBook for detail

Original Measurements:
   McLaughlin, E.; Zainal, H.A., J. Chem. Soc. 1959, 863-867.

Variables:
   Temperature = Temperature

Prepared By:
   W. E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
301.2	0.5852	0.4148
305.6	0.6442	0.3558
318.0	0.8102	0.1898
323.6	0.9013	0.0987

Method/Apparatus/Procedure:
   Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility  determined by noting the temperature at which the last trace of solid solute disappeared.

Source and Purity of Materials:
   (1) Purity not given, Eastman Kodak, Rochester, New York, USA, was passed over an alumina column with light petroleum ether as eluant.
   (2) "AnalaR", was dried over sodium wire and freshly distilled before use.

Estimated Errors:
   Solubility: x₁: ± 0.0003 (compiler).
   Temperature: T/K: precision ± 0.1.
